Aviation safety reports, made easier to study
NTSB Reports is an independent research and search tool for public aviation accident and incident records. It brings NTSB aviation reports, structured fields, docket files, extracted figures, photos, videos, and update history into one searchable interface.
The goal is practical safety education: make it faster to find relevant investigations, compare similar events, review factual records, and understand the evidence behind probable-cause and preliminary reports.
The investigative work and source records belong to the National Transportation Safety Board and the published investigation record. This site is not affiliated with or endorsed by the NTSB.

UPON ARRIVING AT AN AIR SHOW THE PLT WAS GIVEN ADVISORIES FOR A DOWNWIND LANDING. THE ACFT SUBSEQUENTLY GROUND-LOOPED. SUBSEQUENT INSPECTION REVEALED THAT THE TAILWHEEL LOCK HAD ALSO MALFUNCTIONED. THE CENTERING SPRING WAS NOT STRONG ENOUGH TO CONSISTENTLY CENTER THE TAILWHEEL POST SO THAT THE LOCK PIN COULD ENTER. IN ADDITION, THE COMPRESSION SPRING WAS TOO WEAK TO FORCE THE LOCK PIN INTO PLACE.
